Integrated Sensors for Medical Devices and Method of Making Integrated Sensors for Medical Devices

摘要

Methods of manufacturing a sensor for a medical de vice may include the application of semiconductor fabrication techniques to the manufacture of a sensor directly in a structure of the medical device or in a substrate that can be integrated into a medical device structure. The methods may be applied to manufacture position sensors, strain gauges, other transducers, and the like, and to integrate the sensors into a variety of medical device types including, but not limited to, elongate medical devices.

主权项

1. A method of manufacturing a sensor for a medical device, comprising:
providing a tip electrode assembly comprising an atraumatic distal tip portion and a tubular proximal portion; depositing a layer of dielectric material around a longitudinal axis of the tip electrode assembly; depositing a first layer of electrically-conductive material radially outward of the layer of dielectric material to form a plurality of electrically-conductive annular portions; and depositing a second layer of electrically-conductive material to electrically couple adjacent ones of the plurality of electrically-conductive annular portions.
